The car washer 10 includes a well-known car-washing device 20, a top brush 21, a side brush 22, a lower brush 23, inside a car wash room 14 formed by the frame 11.
Cleaning liquid (fresh water, detergent, wax, etc.) nozzle 24, drying top air nozzle 25, drying side air nozzle 26,
A vehicle detection sensor 27, a vehicle shape detection sensor 28, and the like are provided.

However, the car washer 10 is provided with a closing device 30 before and after closing the front and rear openings 12 and 13 of the car wash room 14 to prevent the car washing equipment 20 from freezing and to ensure normal car washing operation in a cold region. , 40 and a hot air supply device 50 for supplying hot air to the interior of the car wash room 14. Hereinafter, specific configurations of the closing devices 30 and 40 and the hot air supply device 50 will be described.

(Closing device 30, 40) Closing device 30 (4
0) is the opening 1 of the car wash room 14 as shown in FIG.
A curtain 31 (41) made of a flexible cloth sheet, a plastic sheet, or the like, which is provided in the car wash room 14 so as to be able to shut off the above-described car washing device 20 from the outside space. Opening / closing drive device 32 that opens and closes with respect to opening 12, and eliminates the slack generated in curtain 31 that is closed with respect to opening 12, and removes curtain 31.
And a control device (not shown) for controlling the opening / closing drive device 32 so as to maintain the closed state of the opening 12 due to the above. still,
When the curtain 31 (41) is closed, the car wash room 14 is closed.
There is no need to seal.

The curtain 31 is connected to a take-up shaft 33 provided along the upper portion of the opening 12 of the frame 11 so as to be able to take up the upper end, and is connected to guide rails 34, 34 provided along both sides of the opening 12 at the lower end. Guide rollers 3 provided on both sides of
5 and 35 are guided by being brought into contact with each other, and a weight 36 is provided at the lower end thereof.

The opening / closing drive device 32 controls the forward / reverse rotational force of the winding motor 37 installed on the frame 11 by a worm speed reducer 38.
By rotating the winding shaft 33 in the forward direction, the curtain 31 is lowered at the opening 12 to close the opening 12, and the winding shaft 33 is rotated in the reverse direction so that the curtain 31 is opened. And the opening 12 is opened. The curtain 31 in the closed state with respect to the opening 12
When a strong external wind is applied to the winding shaft 33, the curtain 31 may play loosely on the winding shaft 33, or the idler of the speed reducer 38 may slack.
2, a gap is formed between both sides of the car wash room 1
There is a possibility that it will be a communication path inside and outside of No. 4 (two-dot chain line in FIG. 5).

Here, the control device of the closing device 30 controls the switch 39 for detecting the lower end of the curtain 31 at the lower end of the opening 12 to guide the sag occurring in the curtain 31 to the guides on both sides of the opening 12.

Can be avoided.

Accordingly, the procedure for opening and closing the curtain 31 (41) by the closing device 30 (40) is performed as follows (FIG. 6).

(1) When there is no car wash customer in the car wash machine 10 for a certain period of time or more, the outside air temperature detected by the outside air temperature sensor is in a cold state below a predetermined cold reaching temperature, for example, 2.5 ° C. Open / close drive 3
2, the curtain 31 is lowered, and the lower end of the curtain 31 is set to the lower limit position where the switch 39 is turned on.

(2) When the car wash machine 10 receives a car wash customer, the curtain 31 of the closing device 30 is raised and the hot air supply device 5
Stop 0. When the vehicle enters the fixed position inside the car wash room 14, the curtain 41 of the closing device 40 is also raised, and both the curtains 31, 41 are set to the upper limit positions.

The hot air supply procedure by the hot air supply device 50 is as follows (FIG. 7). (1) When the outside air temperature detected by the outside air temperature sensor is in a predetermined cold reaching temperature, for example, a cold state of 2.5 ° C. or less, the curtains 31 and 41 of the closing devices 30 and 40 are set to the lower limit position. Under the conditions, the hot air generator 51 is operated to circulate the hot air inside the car wash room 14.

(2) Even if the outside air temperature is 2.5 ° C. or less, if the inside temperature of the car wash room 14 detected by the inside temperature sensor has reached a predetermined set value of the warm-up completion temperature, the hot air generator 51
Stop operation of.

(3) When the outside air temperature exceeds 2.5 ° C., the operation of the hot air generator 51 is stopped. In the car washer 10, the set value of the measurement time by a timer or the like for winding up the curtain 31, the set value of the cold reaching temperature, and the set value of the warm-up completion temperature can be arbitrarily changed.

Therefore, according to the present embodiment, the following operations are provided. The openings 12, 1 of the car wash room 14 are provided by the closing devices 30, 40.
3 is closed and hot air is supplied to the interior of the car wash room 14 by the hot air supply device 50, thereby heating the atmosphere inside the car wash room 14 and scattering at the time of the immediately preceding car wash to scatter the wall surface of the car wash room 14 and equipment for car wash. Water droplets adhering to 20 can be prevented from freezing, and normal car wash operation can be ensured.

The closing devices 30, 40 control an opening / closing drive device 32 for the curtains 31, 41 provided in the openings 12, 13 of the car wash room 14, so that the closed curtains 31,
The slack generated in 41 is eliminated, and the closed state by the curtains 31 and 41 is maintained. Therefore, the curtains 31, 41
The slack immediately closes the gaps generated in the openings 12 and 13 of the car wash room 14, so that cold outside air can be reliably prevented from being blown into the car wash room 14, and the hot air supply device 50 supplies the inside of the car wash room 14. The escape of the heated hot air to the external space can be reliably prevented, and the above-mentioned heated state of the atmosphere inside the car wash room 14 can be stably maintained.

By repeatedly winding and unwinding the curtains 31 and 41 in the closed state at regular time intervals,
The above-described slack generated in the curtains 31 and 41 can be reliably eliminated.

In the car washer 10, the closing device 30
The control device of (40) includes the switch 39 for detecting the lower end of the curtain 31 (41) at the lower end of the opening 12 (13), and connects the slack detection sensor 60 (FIG. 5) of the curtain 31 (41) to the frame 11 May be provided at a specific position inside the opening 12 (13). At this time, the control device
Under the condition that the switch 39 is kept on by the lower end of the curtain 31 (41), when the slack detection sensor 60 is turned on when the curtain 31 (41) is slack, the curtain 31 is turned off until the slack detection sensor 60 is turned off. The opening / closing drive device 32 is controlled to wind up (41). According to this, when the slack detection sensor 60 detects the slack generated in the curtain 31 (41) in the closed state,
By winding up the curtain 31 (41), this slack can be immediately and reliably eliminated.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and the design can be changed without departing from the scope of the present invention. The present invention is also included in the present invention.
